It is impossible for a man to be cheated by anyone but himself.

And

The ancestor of every action is thought

The greatest mistake you can make in life is to continually fear you will make one.

Where you will be and what will you be doing ten years from today if you keep on doing what you are doing now?

And

Where there is nothing to lose by trying, and a great deal to gain if successful, by all means try!

Success is simply a matter of luck, Ask any failure.

Ours doubts are traitors, and makes us lose the good we oft might win by fearing to attempt.

Tge only true happiness comes from squandering ourselves for a purpose.

Men may doubt what you say, but they will believe what you do.
